Though, Its rare phenomena and hasn’t happened in years now.
I used to “Blur out” sometimes where my vision turns blurry and the voices around me become muffled, and unlike spacing out, i am very aware of what’s happening around me / to me.
I usually can snap out of if i want to, by Shaking my head, but its odd because i find very draining to muster the willpower to Shaking my head, feeling very tired
When i was 6, i hit the back of my head against the side of my parents bed. I was jumping on the bed and fell and had to get stitches. Maybe that is the cause of my blurring out?
Assuming you mean mental/sensory blurring and not the thing you get from exhaustion or low sugar or blood pressure:
Yeah, and I think it is linked to meditation and all that shit. As a kid, I used to blur out the voices in a packed bus to pass the time and calm down, for example. Fun little exercise.
I had very similar experiences with psychedelic drugs, and while I am not really into medidation, I occasionally use it as a sort of starting point to, I guess, do a bit of a mental break. First I let the eyes “relax”, then if I’m lucky, the ears and then the brain. If you do that for more than a few minutes, you can end up in some funny mental places.
